What is Cell Theory?
1) All cells arise from preexisting cells.
2) Cells can carry out the processes of life.
3) Organisms are made of cells that function together.
The end products of photosynthesis are?
Oxygen & Glucose
The process of cytoplasm division during plant cell replication is
known as?
Cytokinesis
What principle is this? "An object immersed in a fluid is buoyed up by
a force equal to the weight of the fluid displaced by the object."
Archimede's Principle
Hardening of the arteries is known as?
Arteriosclerosis
Cholesterol known as LDL means?
Low Density Lipoproteins
What does Lock & Key model mean?
A model for enzyme actions
what formula indicates the ideal as law?
PV=RnT
Receiving a vaccine against a disease, what type of immunity is this
considered?
Active.
An alternate form of a gene is called?
allele
, What is an allele?
An allele is one of two or more forms of a gene or a genetic locus. If an
organism has two sets, they are diploid.
The study of the structure of organs and body systems is called?
Anatomy
What is an atom with a negative charge?
anion (- ion)
What is an atom with a positive charge?
cation (+ ion)
what carries blood away from the heart?
arteries
Arteries carry blood away from the heart to the?
Capillaries
What are veins?
carries blood from the capillaries back to the heart (02 poor)
What are arteries?
Carry oxygen rich blood away from the heart
What are capillaries?
Capillaries are the exchange vessels. They are microscopic and have only
one wall—tunica intima—allowing substances to pass through quickly.
What is an atom?
An atom is the smallest unit of matter that still remains the properties of an
element.
what is an atomic mass number?
Equals the total number of protons and neutrons found within the nucleus
of a atom.
What is an atomic number?
the number of protons/electrons that an element has (ex. Carbon's number
is 6: it has six protons; it has six electrons.)
What is an autotroph?
An organism that makes its own food.
What is are vacuoles?
"containers" or holding units in animal cells for water and organic
substances.
what are lysosomes?
-intracellular digestion
What are peroxisome?
Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and
other harmful chemicals
Adenine and guanine are purines that have?
